  1. Volcanoes -- Eruptions
    Volcanoes located within the densely cratered southern highlands have a very different morphology from either the Tharsis or Elysium volcanoes. Tyrrhena Patera has very little vertical relief (< 2 kilometers), resulting in very shallow flank slopes. The flanks of the volcano are deeply eroded with many broad channels that radiate from the summit region. The low relief and easily erodible nature of the flank materials has been interpreted to indicate that the bulk of the volcano is composed of pyroclastic ash deposits. This interpretation implies that the style of eruption for the highland volcanoes like Tyrrhena Patera is significantly different from the repeated effusion of fluid lavas that built up the shield volcanoes.

  2. Etna -- Eruptions
    On 22 June, Etna erupted with lava flowing down the flanks prior to Strombolian activity. Volcanic bombs were thrown ~400 m above the crater and lava fountains reached a height of 150 m. An ash plume rose to ~3 km and very strong degassing was observed at the Bocca Nuova crater. On 24 June, another eruption lasted more than 2 hours. On 27 June, an eruption occurred at the NNE vent on the Southeast Crater. On 28 June and 30, eruptive episodes were ... recorded. Increased degassing was observed at the Northeast Crater on 3 July.
  3. Krakatoa -- Eruptions
    The 1883 eruption of Krakatoa is among the most violent volcanic events in modern times (a VEI of 6, equivalent to 200 megatons of TNT - about 13000 times the yield of the Little Boy bomb which devastated Hiroshima, Japan). Concussive air waves from the explosions traveled seven times around the world, and the sky was darkened for days afterwards. Waves from the tsunamis were recorded as far away as the English Channel. The explosion is considered to be the loudest noise ever heard by man[citation needed].
  4. Pompeii -- Eruption
    Houses in Pompeii tended to face onto an inner courtyard and garden, and the façade facing the street typically was a plain wall. Those facades were often painted with signs and decorated with graffiti. An extreme example is the house on which the name "Trebius Valens" appears 11 times in electoral posters and other messages. Understandably, the house has been attributed to Valens, a Pompeian who was running for magistrate. His fate during the eruption is unknown.
  5. 1980 -- 1980 Eruption
    AFTER: Mount St. Helens four years after the May 18, 1980 eruption, again as viewed from Johnston's Ridge. Note the growth of the lava dome in the crater and the development of the drainage channels around the volcano's flanks.
  6. Mount Vesuvius -- Eruptions
    The most famous eruption of Mount Vesuvius took place in 79 AD and destroyed the city of Pompeii. New geological and archaeological discoveries have shown that another major Vesuvius eruption occurred during the Bronze Age (about 4000 years ago) and was even more devastating.
  7. Sunset Crater Volcano National Monument -- Eruptions
    Wupatki National Monument is several miles north of Sunset Crater Volcano National Monument and was constructed by ancestors of Hopi Native Americans. The area was first settled after the eruption of Sunset Crater Volcano in 1064. The Sinagua people and their Ancestral Puebloan cousins realized that the volcanic ash had made the soil more fertile and consequently favorable for farming. They left the region in the early 13th century. The Wupatki Pueblo shown on this pages was built in 12th century and housed over 100 people. Parts of the buildings had four stories.
  8. 1991 -- Mount Pinatubo
    The June 15, 1991, explosive eruption of Mount Pinatubo, Philippines, was the second largest volcanic eruption of this century and by far the largest eruption to affect a densely populated area. The eruption produced high-speed avalanches of hot ash and gas (pyroclastic flows), giant mudflows (lahars), and a cloud of volcanic ash hundreds of miles across. (U.S. bases have reverted to Philippine control since 1991.)
  9. 1928 -- Miscellaneous
    Many sources attribute the death of up to 5 people to the 1928 eruption, including "an elderly couple" that was overwhelmed by the lava while sleeping. Recent research by Duncan et al. (1996) and Chester et al. (1999) shows that instead, the eruption did not cause any fatalities, because Mascali was completely and orderly evacuated in time and residents not only had the time to save their lives and their households, but movies filmed during the eruption show people removing the rooftiles from their homes before these were engulfed by the lava.
  10. Mount Vesuvius -- Volcanos
    Take a scenic flight over the summit of Mount Vesuvius in Italy, and the view below is chilling. A dense patchwork of urban sprawl from the nearby city of Naples laps at the flanks of one of the most violent volcanoes on Earth. Since A.D. 79, when Vesuvius exploded with little warning and entombed Pompeii and its 3,000 townsfolk under 15 feet of scalding ash, the volcano has erupted at least 30 times.
